Peroneus longus autograft versus hamstring tendon autograft in primary anterior cruciate ligament reconstruction: a systematic review and meta-analysis of randomised controlled trials.

Study Summary

4 randomized controlled trials (RCTs) involving 407 patients undergoing primary anterior cruciate ligament reconstruction (ACLR) were included in this systematic review and meta-analysis comparing peroneus longus tendon (PLT) autografts with hamstring tendon (HT) autografts. Pooled outcomes included Lysholm scores, International Knee Documentation Committee (IKDC) scores, modified Cincinnati scores, knee stability, graft diameter, donor-site morbidity, and American Orthopaedic Foot and Ankle Society (AOFAS) scores. PLT and HT autografts demonstrated comparable knee function and stability, although PLT was associated with better modified Cincinnati scores and fewer donor-site complications. Furthermore, PLT harvesting did not significantly impair ankle function. Overall, PLT appeared to be a promising alternative to HT for primary ACLR, with potential advantages in functional recovery and donor-site morbidity.
